Komari has finally earned a vacation, and she’s soaking it all in at a beach resort. That’s when Nelia Cunningham, a commander from the Gerra-Aruka Republic, appears before her with an outrageous offer: Together, they’ll take over the world. At the same time, a commander from the Heavenly Paradise named Karla Amatsu shows up and hits Komari with the exact opposite proposition: Together, they’ll bring about world peace. Before long, the two nations’ clashing agendas drag the whole world into war! Yanked from her summer holiday, Komari holds the key to the conflict in her hands.
